SIDE FRAME FOR CAR-TRUCKS.

SPECIFICATION forming part of'Letters Patent No. 614,269, dated November'15, 1898.

Application filed Tune 23,1898.

To all whom it may concern:

Be it known that I, FREDERICK I-I. KINDL,

of Pittsburg, in the county of Allegheny and State of Pennsylvania, haveinvented a new and useful Improvement in Side Frames for Oar-Trucks, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, forming part of thisspecification, in which Figure 1 is an elevation of my improved sideframe, the left-hand half being an outside View and the right-hand sidebeing an inside view. Fig. 2 is a plan view. Fig. 3 is an end view, andFigs. 4 and 5 are cross-sections on the lines IV IV and V V of Fig. 1.

My invention relates to the side frames employed upon car trucks, and isdesigned to stiffen and strengthen what is known as the arch-bar type ofside frame and to do away with the vertical through-bolts heretoforeemployed with such frames.

In the drawings, 2 represents the top member, which consists of anangle-line having its central portion bent into arch form, while itsends 3 3 form the tops of the pedestals. To these end portions 3 3 areriveted corresponding end portions 4 4 of another angleiron 5, havingits flanges projecting in the opposite direction from its'upper edge,the intermediate part of this angle being bent into depending arch formand extending along the base of the bolster-opening, across the top ofwhich the upper arch angle-bar extends.

6 6 are web-plates which are riveted to the angle arch-bars and extendon each sidefrom the bolster-opening to the pedestal. A lower horizontalangle-iron 7 is riveted to the lower ends of these plates and to thelower portion of the depending arch-angle. The sides of each pedestalare formed by vertical anglebars 8 and 9, of which the bar Sextendsbetween the portion 3 of the upper angle and the lower angle 7, and isriveted directly to the web-plate 6, while the ends of the angle 9 areshaped to fit between the angles 3 and 4: by cutting away the endportions of the flanges. This angle-iron 9 is removaly bolted in placeby bolts 10, the upper of which passes through the webs of the angles 3and 4, while the lower passes through the web of the angle 7 and througha plate 11, riveted to a filler- Serial No. 684,293. (No model.)

plate 11, which extends along the baseof the pedestal and is riveted tothe web of the angle 7. The bolts are thus placed in double shear. 7

At the sides of the bolster-opening are provided pairs of verticalangle-irons 12 and 13, both of which extend downward to the level of theangle 7, while the one 12 extends to the lower face of the upper angle 2and the other extends to the top of such angle, its flange preferablybeing cut away at an angle, as shown at 14.. These angles 12 and 13 areriveted to each other through the web-plate, as shown. To strengthen theupper part of the frame above the bolster-opening, I rivet to the angle2 the short angle 15, which extends between the pairs of angles formingthe sides of the opening.

This side frame is applicable to different forms of trucks and presentsmany advantages both in strength and stifiness and in cheapness ofbuilding. It is formed from commercial shapes, and the journal-boxes maybe easily removed endwise from the pedestals by loosening the bolts ofthe angle 9 and slipping out this angle.

Many variations may be made in the form of the arches and the joints ofthe various parts without departing from my invention.

I claim- 1. An arch-bar side frame having upwardly and downwardlyextending arch-shaped members of angle-bar material substantially asdescribed.

secured to the angle-iron arch-bars; substan-' tially as described.

5. An arch-bar side frame, having upper and lower arches formed ofangle-bar material,,the ends of these angle-bars being-secured togetherabove the pedestal and a lower horizontal extending angle-iron formingthe base of the pedestals and secured to the lower arch-bar;substantially as described.

6. An arch-bar side frame having an upper and lower arch-bar each formedof angle-iron material, Web-plates secured thereto between the centralopening and the pedestals, and vertically-extending angle-irons securedto the arch-bars and to the web-plates; substantially as described.

7. An arch-bar side frame, comprising an upper and lower arch-bar, eachformed of angle-iron material and having their ends secured togetherabove the pedestals, a lower horizontal angle-iron forming the base ofthe pedestals and the central opening, web-plates secured to thearch-bars and the horizontal angle and extending between the centralopening and the pedestals, and vertical angle-irons forming the sides ofthe pedestal and the sides FREDERICK H.
